CO'MBINED ROTARY-DISK HARROW AND SE E D SOWER.

SPEQIFICATION- forming part of Letters Patent No. 282,526, dated August'7, 1883.

Application filed March J1, 1883.

To all whom it may concern.-

Be it known that I, J OHN I LER, a citizen of the United States,residing at Zionsville, in the county of Boone and State of Indiana,have invented a new and useful Improved OombinedRotary-Disk Harrow andSeed-Sower, of which the following is a specification,

having reference ings.

to the accompanying draw- My improvement relates to ameans for combininga rotary-disk harrow with a seed-sower;

the harrow may be raised out of contact with Y the ground or set toenter the ground to any desired depth; and, third, to so combine andconnect the two machines that the seed-sower will be thrown out of gearsimultaneous with.

and by the same operationthat raises the harrow out of the ground.

The accompanying drawingsillustrate my in vention.

. plan.

Figure 1 is a side elevation. Fig. 2 is a Fig. 3 is an enlarged partialplan with the seed-boxremoved, showing the connection between the axleof the seedsower and the feed-wheel shafts. Fig. 4is a front elevationwith the harrow removed.

Like letters indicate the same parts in all figures.

a represents the frame of an ordinary disk harrow; b, the draft-poleattached to saidframe.

0 represents the seed-box, d the axle, and e the feed-shaft, of anordinary seed-sower without draft-pole or opening-hoes. Across the frontof the seed-box a shaft, f, is secured in suitable bearings, so that itis free to partially revolve. Shaft fis provided with arms 9 g, rigidlysecured thereto, and also shorter arms h h, similarly secured. Arms 9have an eye or bolt-hole at the outer end of each, by means of whichthey are connected to the top of harrow-frame a by bolts u u, passingthrough the lugs 13 c and said arms. A lever, j, is fastened on theshaftf, and is provided with a sliding pawl, k, which engages a{segment-rack, Z, fastened to the seed-box. The axle (l is in two parts,which revolve in chains. t

For thepurpose of preventing the seed- (No model.)

suitable bearings secured to the seed-box, the carrying-wheels m n beingrigidly secured to said axle. The inner end of each section of the axleis furnished with a loose pulley, o 0, and said pulleys are connected bybelts with fast pulleys on the feed-shaft. Sliding clutches p p l oneach section of the axle revolve therewith,

and are thrown into and out of connection" with pulleys 0 0 by means ofbell-crank le-. vers r r. For the purpose of operating said leverssimultaneously with and by the same operation that theharrow-frame israised, and thereby raising the harrow out of the ground and stoppingthe dropping of the feed at the same time, arms h h are connected withthe short arms of levers r a" by means of short sower from turning ortipping backward on its axle,-a brace-rod, s, is secured to the seedbox,as shown, which, running forward, passes through aneyebolt, t, in theunder side of the tongue in such manner that the brace rests to theseed-sower by meansof the lever j,

turning shaft f and raising arms 9 9, being retained in position by thesegment-rack Z and pawl 7c. As the shaft f is turned in raising theharrow the clutches p pare slid on the axle and disengaged from thepulleys 0 0 by the raising of the short arms h h, operatingbell-cranklevers o" 1', and the feed movement of the seed-soweristhereby stopped. By simply removing bolts to a the harrow isdisconnected from the seed-sower, and may then be used independently.

I claim as my invention 1. I11 a combined rotary-disk harrow andseed-sewer, the shaft f, arms 9 g and h h, 1ever j, pawl 70, and rack Z,bell-crank levers r r, clutches 1) p, and pulleys o 0, all combined inthe manner and for the purpose specified. 2. Ina combined rotary-diskharrow and seed-sewer, brace-rod s, secured to the seedsower, and meansfor detachably securing the free end of said rod to the draft-pole,substantially as shown and described.
